Error : There is no row at position 1, Using DataRowVersion

[alokmishra2003]

I am using a grid, in which dynamically creating some columns and rows and EDIT buttons. While Updating the rows I am comparing DataRowVersion. Original and DataRowVersion. Current .

Its working fine when I did it first time, but when do it second time for another Edit and Update button. It shows the similar problem.
"There is no row at position 1"
Here is the code in Update button.

showMessage(){
  var message = document.getElementById('<%=Message.ClientID %>');
  if(message)
  {
    message.style.display='block';
  }
}
for (int i = 0;i < dtDataChange.Columns.Count;++i)
{
   if (Convert.ToString(dtDataChange.Rows[iIndex][i, DataRowVersion.Original]) != Convert.ToString(dtDataChange.Rows[iIndex][i, DataRowVersion.Current]))
  {
    String sCol = dtDataChange.Columns[i].ColumnName.ToString();
    String sVal = dtDataChange.Rows[iIndex][i].ToString();
 
  }
}

Thanks for helping hands in advance.

I got my answer this time from some other place.

Alok,

You have mistakenly posted in the ASP Classic forum instead of the ASP.NET forum. I have moved your post for you. I am glad you found an answer. Is there any chance you could post it here?

What was the answer?

[alokmishra2003]

I was using iIndexin above code, insetad of this I was to use only [0]. After that after clicking in any row I got all the correct values from the grid.

I was clicking first row UPDATE button first, all the time, so didnt get any error first time, because its Index was 0. But when next time I clicked UPDATE button of some another row, then it creates the problem.
Thanks & Regards
